in_voluntarymuscles  We have two types of muscles: voluntary and involuntary.

VoluntaryMusclesWe can move voluntary muscles when we want. We decide to do something and our brain sends a signal to these muscles.

InvoluntaryMusclesWe can’t control involuntary muscles. They move automatically.

HeartInvoluntaryMuscleOur heart is an involuntary muscle. It moves all the time without us thinking about it, even when we’re asleep!

StomachInvoluntaryMusclesThere are also involuntary muscles in our stomach that help us digest our food.
